1 Infineon Technologies Corp. June 99 1 HOT167-1 Version 2.0 * C167CS not yet supported by DAvE V1.0 CD ROM. See “Hints regarding DAvE.” Exercise 7ASC_1 - DAvE Configurations  Start DAvE  Create new Project with microcontroller C167CR/CS* Project name: 7ASC_1 Select project path: c:\hot167_1\7asc_1  Project Settings: General: -Select Keil Compiler, SMALL model System Clock: -External Oscillator Frequency: Set to 5 MHz Startup Configuration: -Bus Type after Reset: Set to 16 bit DEMUX -Write Configuration: Pin #WR and #BHE operates as #WRL and #WRH Save & close

2 Infineon Technologies Corp. June 99 2 HOT167-1 Version 2.0 Exercise 7ASC_1 - DAvE Configurations (cont.)  Configure GPT1: Core Timer 3: -Timer 3 Mode: Timer Mode -Up/Down Control: Count down -Timer Start: Start T3 after initialization -Input Selection: Fcpu/16 (this results in a resolution of 0.8us and a period of 52.4ms) -Timer Register: Load T3 Register with 10ms value ((10ms / 0.8us) in HEX) (0x30d3) -Interrupt Control: Enable Timer 3 interrupt Auxiliary Timer 4: -Timer 4 Mode: Reload Timer 3 with T4 -Timer Register: Load T4 Register with 10ms value ((10ms / 0.8us) in HEX) (0x30d3) -Input Selection: Any transition of output toggle latch T3OTL

3 Infineon Technologies Corp. June 99 3 HOT167-1 Version 2.0 Exercise 7ASC_1 - DAvE Configurations (cont.)  Configure GPT1 (cont.) Interrupts: -Choose interrupt level for GPT1 Timer 3 interrupt Functions: -Include GPT1 initialization function GT1_vInit Save & close  Configure ASC USART: Control: -Global: Use pin TxD0 for ASC -Receiver: Enable Receiver (S0REN) Baudrate: -Required Baudrate: Depends on your debugger configuration; Default after installation is 9600 baud Functions -Include ASC_vInit, ASC_vSendData Save & close  Generate Code

4 Infineon Technologies Corp. June 99 4 HOT167-1 Version 2.0 Exercise 7ASC_1 - µVision2 Configurations  Start µVision2  Open Project c:\hot167_1\7asc_1\7asc_1.uv2 (Project | Open Pr.)  Add Files: Go to Project | Targets, Groups, Files… Click ‘Groups / Add Files’ Select ‘Source Group 1’ Click ‘Add Files to Group’ Select all C files and click ‘add’ ???Enter file name ‘start.asm’, click ‘add’ (Assembler Startup File) Click ‘Close’ and ‘OK’ Double-click all files in the Project Window to open them  Select Target Hardware (kitCON-167): Go to Project | Options for Target ‘Target 1’ Go to ‘Debug’ tab Click ‘Settings’ (upper right hand corner) Monitor configuration: select ‘Phytec KC167’ Click ‘OK’ twice

5 Infineon Technologies Corp. June 99 5 HOT167-1 Version 2.0 Exercise 7ASC_1 - µVision2 Configurations (cont.)  Edit MAIN.C: include endless loop in main(): // USER CODE BEGIN (Main,2) while(1) {}; // USER CODE END  Edit GT1.C: Define Global Variable ascii_char: // USER CODE BEGIN (GT1_General,2) unsigned char ascii_char; // USER CODE END In Timer 3 Interrupt Service Routine (GT1_viIsrTmr3(void)): Write ascii_char to ASC and increment ascii_char: // USER CODE BEGIN (GT1_IsrTmr3,1) ASC_vSendData(ascii_char++); // USER CODE END

6 Infineon Technologies Corp. June 99 6 HOT167-1 Version 2.0 Exercise 7ASC_1 - Running the Program  Reset Target Hardware (Press Reset Button on Starter Kit)  Build Project (Project | Rebuild Target)  Run integrated Debugger from within µVision2 Debug | Start / Stop Debug Session (click ‘OK’ when prompted) The Debugger will load the Keil Monitor into the kitCON-167’s RAM via bootstrap loader Object file c:\hot167_1\7asc_1\7asc_1 will be loaded automatically and the debugger will go to main().  Go! (Debug | Go)  Program Verification: Watch Serial Window in Debugger (View | Serial Window #1) (right mouse button lets you switch between ASCII and Hex output) Connect Scope to P3.10 / TxD0 (connector X3 pin 110) (select 200 us/Div, trigger on falling edge) Hint: When stopping the program, override the appearing error message by pressing “continue”. The program will stop.
